14 imers eneral Instructions eneral Instructions for All imer Series Load Current With inductive, capacitive, and incandescent lamp loads, inrush current more than 10 times the rated current may cause welded contacts and other undesired effects. he inrush current and steady-state current must be taken into consideration when specifying a timer. ime Setting he time range is calibrated at its maximum time scale; so it is desirable to use the timer at a setting as close to its maximum time scale as possible. For a more accurate time delay, adjust the control knob by measuring the operating time with a watch before application. Contact Protection Switching an inductive load generates a counter-electromotive force (back EMF) in the coil. he back EMF will cause arcing, which may shorten the contact life and cause imperfect contact. Application of a protection circuit is recommended to safeguard the contacts. emperature and Humidity Use the timer within the operating temperature and operating humidity ranges and prevent freezing or condensation. After the timer has been stored below its operating temperature, leave the timer at room temperature for a sufficient period of time to allow it to return to operating temperatures before use. Environment Avoid contact between the timer and sulfurous or ammonia gases, organic solvents (alcohol, benzine, thinner, etc.), strong alkaline substances, or strong acids. Do not use the timer in an environment where such substances are prevalent. Do not allow water to run or splash on the timer. Vibration and Shock Excessive vibration or shocks can cause the output contacts to bounce, the timer should be used only within the operating extremes for vibration and shock resistance. In applications with significant vibration or shock, use of hold down springs or clips is recommended to secure a timer to its socket. iming accuracies are calculated from the following formulas: Repeat Error Voltage Error v : Average of measured values at voltage V r: Average of measured values at the rated voltage emperature Error iming Accuracy Formulas = ± 1 x Maximum Measured Value Minimum Measured Value x 100% 2 Maximum Scale Value = ± v - r x 100% r Input Contacts Use mechanical contact switch or relay to supply power to the timer. When driving the timer with a solid-state output device (such as a two-wire proximity switch, photoelectric switch, or solid-state relay), malfunction may be caused by leakage current from the solid-state device. Since AC types comprise a capacitive load, the SSR dielectric strength should be two or more times the power voltage when switching the timer power using an SSR. enerally, it is desirable to use mechanical contacts whenever possible to apply power to a timer or its signal inputs. When using solid state devices, be cautious of inrushes and back-emf that may exceed the ratings on such devices. Some timers are specially designed so that signal inputs switch at a lower voltage than is used to power the timer (models designated as B type). = ± t - 20 x 100% 20 t : Average of measured values at t C 20 : Average of measured values at 20 C Setting Error = ± Average of Measured Values - Set Value x 100% Maximum Scale Value he maximum scale value of the 3P equals the preset time for one cycle.
